The whole point of bio active substrate is to never have to change it or at least go a long time with out. And the "bio-active" part is from the tiny bugs that live in the substrate with out them its just normal substrate. You can turn Almost anything into Bio-Active substrate from bark to soil to moss to aspen. Just colect items from outside like bark,wood and leaf litter. Or you can add your own bugs like spring tail and isopods. I believe "BarelyBreathing" Has a thread up about the different types she uses search her threads and you should find it.
Also im using top soil and Childrens washed play sand. You can also dig up you own substrate.
